TYPE-WRITING MACHINE.

To all whom it may concern:

Be it known that I, GHQ 13. Law, citizen of the United States, andresident of the borough of Brooklyn, city of New York, in the county ofKings and State of New York, have invented certain new and usefulImprovements in Type-l/Vriting Machines, of which the following is aspecification.

My invention relates to paper supply and paper feeding means fortypewriting machines and its object, generally stated, is to provideimproved devices of the classes specified.

. To the above and other ends, the invention consists in the features ofconstruction, combinations of devices and arrangements of partshereinafter described and particularly pointed out in the claims.

My invention is concerned chiefly with providing improved supporting andfeeding means for a tally or checking strip, which strip isadvantageously employed to facilitate and improve the methods used insome systems of commercial billing, such, for example, as the systemoutlined in my companion application No. 365,953, filed April 2nd, 1907.In said companion application I have shown a tally strip mounted on apair of rotary carriers which are arranged on the carriage of atypewriting machine, which tally strip is adapted to pass over one endof the platen around and outside of the bill sheet and to beautomatically line spaced when certain paper controlling devices0perative on the bill sheet are actuated.

In the present embodiment of my invention, a single tally strip holderis mounted on the carriage of the machine and the tally strip is fedfrom said holder over a short supplementary platen or platen sectionarranged at the right of the main platen or platen section and providedwith separate paper feeding devices and separate line spacing deviceswhich are operative by the stop positioning and paper releasingmechanism of the machine and independently of the line spacing mechanismwhich controls the main platen or platen section.

The details of the construction will be eX- plained more fully inconnection with the accompanying drawings, wherein,

Figure 1 is a fragmentary end view, partly in section, of the upper partof a No. 8 Be1n ington typewriting machine showing my invention appliedthereto. Fig. 2 is a frag- Specification of Letters Patent.

g in Fig. 3 and looking in the direction of the arrows at said line,parts shown in said Fig. 3 being omitted in Fig. 5 and other parts beingshown in the latter figure in different positions from those in whichthey appear in Fig. 3. Fig. 5 is drawn to the same scale as Fig. 4. Fig.6 is a vertical longitudinal sectional view of the tally strip holder asseen from the rear and looking forwardly, the support of said holderalso being shown. Fig. 7 is a longitudinal sectional view of asupplementaryfeed roller and its mounting, said feed roller cooperatingwith the supplementary platen section. Fig. 8 is a horizontallongitudinal sectional view of the tally strip holder, the rear side ofthe holder being nearest the observer, said view also showing thesupplementary feed roller supported on said holder.

Although I have shown my invention as applied to a No. 8 Remingtontypewriting machine, it is to be understood that said invention may beembodied in other forms of writing machines.

Referring first to Figs. 1, 2 and 3 of the drawings, the main frame ofthe machine comprises a base frame (not shown) from which rise cornerposts 1 supporting a top plate 2. A fixed groove track-way 3 issupported on the top plate and receives bearing rollers 4, said rollersalso cooperating with a grooved track-way 5 secured on a carriage truck6. The usual connections, comprising slide bars 7 and links 8 connectthe carriage truck with the platen carrier, said carrier comprising arear bar 9, side or end bars 10 and a front bar 11. Guide rollers 12carried by a bracket 13- fixed to the front bar of the carriage engageat opposite sides a shift rail 14 which is carried by arms 15 pivoted inthe usual manner at their lower ends to the machine frame. The shiftrail 14, it will be understood, is movable at will to shift the platencarrier fore-and-aft of the machine on the carriage truck, this shiftingmovement being for the purpose of changing from lower to upper case andvice versa and being limited by adjustable screw stops 16, supported onthe carriage truck 6 and cooperating with stop pins 17 projectinglaterally from the usual extensions or arms 10 rising from the rearportions of the side bars'lO. Besides its sliding motion on the carriagetruck the platen carrier has a pivotal movement for the purpose ofexposing the writing. The carriage truck and platen carrier comprise theplaten carriage which supports a sectional or divided platen, the

details of which are shown clearly in Fig. 2.

The platen is supported on a shaft or axle 18 which has bearings on theside bars 10 of the platen carrier. The long or main platen or platensection comprises a wooden core 19 inclosed in a sheath 20 of rubber orthe like. A platen head 21 is secured to the left end of the main platensection by wood screws 22, said platen head being fixed by a set screw23 to the platen axle. The righthand end portion of the core 19 isreduced as indicated at 24, and surroundin this reduced ortion is a thinsheath 0 metal 25 which 1s prevented from turning relatively to the coreby pins 26. Near its ends the sheath 25 is provided with raised circulartracks 27 which support and serve as bearings for the metal core 28 ofthe short or supplementary platen or platen section which furthercomprises a sheath 29 of rub.- her or the like secured in a fixedrelation to the core 28 by screws 29*. The short platen section is inthe nature of a shell which is supported on and adapted to turn on thelong platen section, said platen sections or platens having coincidentaxes of rotation. The outside diameter of the short platen section issomewhat less than the outside diameter of the long platen section, asclearly appears in Fig. 2. The right-hand end portion of the core 28 isthickened and formed with peripheral ratchet teeth 30 forming a ratchetwheel cooperative with supplementary line spacing devices hereinafter tobe described. An extension 31 on the core 28 outside the ratchet teethengages loosely in a groove formed between the end of the sheath 25 anda shoulder 32 formed on the right-hand platen head 33 of the main platensection. The platen head 33 is secured to the core 19 by long screws 34which engage threaded openings in metal blocks 35 set in the core 19.The engagement of the annular extension 3,1 on the supplementary platenwith the groove in the main platen prevents endwise movement of thesupplementary platen relatively to the main platen, but permits saidsupplementary platen to turn freely on its support. The platen head 33is provided with peripheral ratchet teeth 36 forming a ratchet wheelcooperative with which is the usual line spacing pawl 37 (Fig. 1), thelatter being pivoted at 38 to the upper arm of an angular line spacinglever 39, which is operative in the usual way to communicate rotary linespace movements to the main platen section. A roller detent 40 (Figs. 4and 5), pivoted to a spring arm 41 secured to the under side of thefront bar 11 of the platen frame by a headed screw 41", constantlyengages with the ratchet teeth 30 on the supplementary platen sectionand tends to prevent turning movements of said section, except ashereinafter described. The construction is such that the supplementaryplaten section is not affected by the operation of the line spacinglever 39, so that the main platen section may turn while thesupplementary platen section remains quiescent. The usual roller detent42 (Fig. 1) carried on a spring arm 42 suit ably secured to the platencarrier, cooperates with the line spacing ratchet wheel on the mainplaten section to hold said platen section from accidental movement. andthe construction is such that the main platen section may remainmotionless while the supplementary platen section is turned as will moreclearly appear hereinafter.

Referring now to the paper controlling devices for the main platensection, these are the same essentially as those shown in my companionapplication and will be only briefly described at this place, saidcompanion application being available for a fuller description. As shownin Figs. 1, 3, 4 and 5, the supports for the main feed roller comprisetwo sets of brackets 43 secured by screws 44 to the rear bar 9 of theplaten carrier, said screws also securing feed roller pressure springs45 in place. Each bracket 43 pivotally supports a Y-shaped hanger arm46, the hanger arms carrying feed roller shafts 47 on which are mountedfeed roller sections 48. In the present case the feed roller section 48,nearest the sup plementary platen section, is shortened somewhat morethan the other feed roller sections 48, so that it terminates at oneside of the supplementary platen section. It will be understood thateach pair of hanger arms carries a feed roller shaft, the two hangerarms of each pair being spaced apart at one side of the middle of theplaten frame. Each shaft 47 carries two feedroller sections so that inthe present instance there are four feed roller sections in all, whichare normally maintained in contact with the platen or the paper thereonby the pressure springs 45. It is to be understood, however, that thoughthis is a convenient and eflicient arrangement of the main feed roller,yet insofar as my present invention is concerned other arrangements offeed roller sections or a single long feed roller may be employed. Eachhanger arm 46 is provided with a lug 46 cooperative with which is a fin49 fixed to a rock shaft 50 extending from side to side of the platencarrier at the rear thereof, said rock shaft at its right-hand endbearing on a screw pivot 51 and at its left-hand end extending through abearing opening in the left-hand side bar 10 of the platen carrier andbeyond said side bar. The rock shaft is controlled by a manuallyactuated arm 52 which is se cured to the left end portion of the rockshaft by a set screw 53 (Figs. 1 and 3). The arm 52 is formed at itsrear with a slot 54 which receives a detent or latch 55 pivoted at 56and provided with a spring 57 and an engaging lug 58, the latter beingcotiperative with a notch or cut-away 17 a formed in the left-hand stoppin 17.

A U-shaped stop frame or bar 59 extends lengthwise of the platen behindthe main feed roller and is provided with ears 59 which receive headedscrews 60 by which the stop frame is secured to bearing blocks 61, thelatter being mounted loosely on the rock shaft 50. The stop bar isprovided at intervals with curved arms 62 which carry housings 63containing spring-pressed stop pins 64 which are adapted to contact withthe platen between the sections of the main feed roller, althoughnormally they are separated from the platen as clearly shown in Figs. 1and 4 by wire springs 65 acting on the stop bar frame to hold the latterand the stop pins in the positions shown in said figures. As shown inthe rear view (Fig. 3) the lefthand bearing block 61 is cut-away to forma shoulder 61 and cotiperative with this shoulder is a shoulder 66formed on a collar 67 fixed to the rock shaft 50. Normally theseshoulders 61 and 66 are separated but when the rock shaft 50 is turnedor rocked rearwardly by the arm 52 the shoulder 66 is adapted to engagewith the shoulder 61 and overcoming the springs 65 to swing the stop bar59 and stops 64 forwardly and upwardly toward the platen, bringing thestops 64 into contact with the platen or the paper thereon. The partsare arranged so that this movement of the stops 64 will not take placeuntil after the main feed roller has been released or moved away fromthe platen by the cotiperation of the fins 49 on the rock shaft 50 withthe lugs 46 on the arms 46 which carry the main feed roller sections. Itwill be understood that when the arm 52 is pushed rearwardly and lockedin the position indicated by the dotted lines in Fig. 5 (which lockingis caused by the cooperation of the lug 58 with the notch 17 in the stoppin 17 the main feed roller will be released and the stop pins 64 willbe rendered operative as shown in said Fig. 5.

In employing the paper controlling devices above described, whichdevices comprise a paper stop device and a paper feeding device, a worksheet may be entered in the machine over a paper table (not shown) andpassed down between the usual paper apron 68 and the platen, thencebetween the platen and the feed rollers and then upward and outwardbetween the platen and the usual paper fingers or devices which areconventionally shown in Fig. 1 and desig nated by the numeral 69. Insystems of billing work in which the use of my present invention iscontemplated and in which bills are rendered monthly or at other statedperiods and entries on said bills are made from day to day during themonth as purchases are made, it is important that each time the billsheet is introduced into the machine for the purpose of printing a newitem thereon, said bill sheet should be started to be fed forward by theline spacing devices from the same point in order that the first line oritem of the new entry shall be spaced at a regular and proper distancefrom the last line of the immediately preceding entry. For this reasonit is highly desirable to employ a device for properly alining andpositioning the work sheet each time it is entered in the machine, suchas the paper stop device above described. In employing this device inthe present instance, after the entry on one bill has been written andit is desired to remove the written bill and introduce another bill intothe machine, the operator first presses rearwardly against the arm 52until the latter is locked in the position shown by the dotted lines inFig. 5. By this movement of the arm 52 the bill sheet then in themachine will be released from the con trol of the main feed roller andthe stops 64 will be brought into operative positions. The leading edgeof the next bill sheet may now be introduced into the machine and moveddownwardly over the paper table and paper apron and between the platenand the main feed roller until the leading edge of said bill sheetcontacts with the stops 64. The locking of the main feed roller and theleading edge stop device in the positions illustrated in Fig. 5 enablesthe operator to have the use of both hands to enter the new bill sheetand square or aline it by the aid of the leading edge stops 64. It willbe understood, however, that though this locking feature is a desirableone it is not essential in the present case. The bill sheet having beenthus alined the arm 52 may be released and the parts of the papercontrolling devices restored to normal position.

From the operations above described it will be understood that means areprovided for squaring each bill sheet as it is introduced into themachine and for starting it off under the control of the line spacingdevices from a predetermined position, which position is of course thesame for all of the bill sheets.

The novel tally strip devices which I prefer to employ in the presentinstance will now be described. As best shown in Figs. 1, 8, 4 and 6 acurved supporting arm or bracket is detachably secured to the front bar11 near its right-hand end. Said arm or supporting bracket is notched asindicated at 71 to cooperate with the rearwardly extending lip of thefront bar 11 and is connected by a headed screw 72 with a clamping plate7 3 which is formed with a similar notch cooperating with the forwardlip of the bar 11. The screw 72 passes loosely through an opening 74L inthe clamping plate 73 and the latter is maintained in proper relationwith the arm or bracket 70 by an adjusting device or headed screw 75which is supported in the plate 73 and abuts against the arm 70. Theconstruction is such that by means of the two screws 72 and 7 5 and theclamping plate 73, the arm 70 is maintained in a fixed relation with theplaten carrier but may be readily removed therefrom by loosening thescrews 72 and 75. The arm 70 curves upward and rearward over thesupplementary platen section near its right-hand end and terminatesabove the platen in an enlargement or boss 70 which is perforated toreceive a headed screw 76 by which the tally strip holder or carrier issecured to the arm 70. The tally strip holder or carrier, as best shownin Figs. 6 and 8, comprises right and lefthand heads numberedrespectively 77 and 78, the inner faces of said heads being formed witharcuate grooves which receive a trough-like shell or cradle 79, thefront and back edges of which terminate slightly below the centers ofthe heads 77 and 78 as will be best understood from an inspection ofFig. 4;. The heads 77 and 78 are also formed with an annular groove 80outside the groove which receives the trough or cradle 79, said groove80 serving as a track or way for a curved cover plate 81 the latterbeing provided with a handle 82 by which it may be turned back and forthin its grooved tI'ELClGWZLYS 80. The cover plate is illustrated in Fig.4 in closed position and on inspection of this figure it will be notedthat a narrow slot or passage-way 83 extends between the back edges ofthe cover plate 81 and the trough 79. By pressing the handle 82forwardly the cover plate may be turned to widen the opening 83 until itis almost equal to the full diameter of the tally strip holder. In thislatter position of the cover plate the supplementary work sheet or tallystrip, subsequently to be described, may be readily inserted in itsholder or removed therefrom. The heads 77 and 78 are connected by threerods or bars 84 which are spaced apart as shown in Fig. 4. Each of therods passes from one head to the other and receives at each end a screw85 which passes through an opening in a lug 86 projecting outwardly fromthe periphery of the head of which it forms a part. This construction isclearly shown in Fig. 8. By the means thus described the heads 77 and 78are securely held in a fixed relation with each other. The right-handhead 77 (which is seen at the left side of the tally strip holder inFigs. 6 and 8) has a threaded opening at its center which cooperateswith the screw 7 6 by which the tally strip holder is secured to thesupporting arm 7 0. A sleeve 87 is arranged on the shank of the screw 76between the arm 70 and the tally strip holder, said sleeve serving toproperly position said holder with respect to the supplementary platensection. A pin 87 (Fig. 8) passes through the head of the screw 7 6 andthence through the boss 7 0 the sleeve 87 and the head 77. Said pinprevents the accidental loosening of the screw 76 and also prevents thetally holder from turning relatively to its supporting arm 70. Thesupplementary work sheet or tally strip, designated by the numeral 88,is wound into a roll together with a strip of carbon paper 89 andinserted in the holder in which it loosely lies, or floats as it istermed. The outer or free ends of the tally and carbon strips are drawnthrough the opening 83 and downwardly bet-ween the trough 79 and therear connecting bar 84, passing over the paper apron 68 and around thesupplementary platen section and upwardly between the front of the coverplate 81 and the forward connecting rod or bar 84, the rear portion ofwhich is cut away as indicated at 84:. The forward bar 84. is providedwith a groove in which is set a cutting blade 91 (Figs. 4, 6 and 8) bywhich the tally strip may be conveniently severed when desired. Thepaper apron (38 is a paper guiding device common to the two work sheets.

Supplementary paper feeding devices are provided for the tally andcarbon strips, said devices comprising a supplementary feed roller whichcooperates with the supplementary platen section. The details of thissupplementary device or feed roller are best shown in Fig. 7. Itcomprises a sheath 92 of rubber or the like surrounding a wooden core 93which is driven on a metal sleeve 94;, the latter being adapted to turnon an axle or rod 95 which is supported near its ends by arms 96 and 97which are hung from the tally strip holder. As shown in the drawings thearm 96 is integral with the axle 95, which axle terminates in a handle98 extending beyond the arm 96. The opposite end of the axle is reducedand threaded as indicated at 95 to receive the arm 97, the latter beingprovided with an opening which fits over the reduced portion 95 andbeing clamped by a clamping nut 99 against the shoulder formed betweenthe body of the axle and its reduced end 95. The construction is suchthat the arms 96 and 97 are normally fixed relatively to the axle butthe arm 97 may be removed in order to permit of the withdrawal of thesupplementary feed roller. The arms 96 and 97 extend upwardly andforwardly from the supplementary feed roller, as shown in Figs. 1, 3, 4and 8 and are formed with round holes at their upper ends through whichloosely pass headed and shouldered screws 100, said screws engagingthreaded openings in the heads of the tally strip holder. Coiled springs101 are secured at their lower ends to pins 102 projecting laterallyfrom the arms 96 and 97.

.The upper end of the left-hand spring is hooked over a pin 103projecting laterally from the head 78 and the upper end of theright-hand spring 101 is hooked on a lug 87 formed in the sleeve 87(Figs. 3 and 8). The springs 101 serve normally to maintain thesupplementary feed roller in engagement with the supplementary platensection or with the paper thereon as shown in Figs. 1, 3 and 4. Whendesired, as when a new tally strip is to be introduced, thesupplementary feed roller may be released or thrown up to inoperativeposition by means of the handle 98. Normally the supplementary feedroller is so positioned that it is cooperative with the tally and carbonsheets somewhat to the rear of the top of the platen.

The supplementary feed roller terminates at one side of the main platensection and does not therefore coiiperate with the latter (see Fig. 3)and, as has already been explained, the main feed roller does notcooperate with the supplementary platen section. In other words, themain and supplementary platen sections have independent paper feedingdevices. It will be apparent that when the supplementary platen sectionis turned in line spacing direction by means presently to be described,the supplementary feed roller will operate on the tally and carbonstrips to feed them forward past the printing point and to unwind acorresponding portion from the floating roll or tally strip within thetally strip holder.

Referring now to the means for turning the supplementary platen sectionand line spacing the supplementary work sheet or tally strip, said meanscomprises an arm 104 which surrounds the rock shaft 50 near itsright-hand end and is secured in a fixed relation therewith by a setscrew 105 (Figs. 3, 4 and 5). The arm 104 extends upward and forward atthe rear of the platen and at its upper end is pivotally connected witha gravity pawl 106 at 107. At its forward end the pawl 106 is providedwith a pawl tooth 108 which engages with the ratchet wheel on thesupplementary platen section and is prevented from being thrown backaccidentally to inoperative position by a tail piece 109 extendingrearwardly from the body of the pawl, said tail piece being adapted tocontact with the rear or outer face of the arm 104. When the rock shaft50 is rotated rearwardly by means of the arm 52 to operatively positionthe stops 64 and release the main feed roll, the arm 104 will be turnedrearwardly with the rock shaft, moving the pawl 106 from the positionindicated in Fig. 4 to that indicated in Fig. 5. This movement of thepawl effects, through the ratchet wheel 30, a turn ing movement of thesupplementary platen section, resulting in a line space feeding movementbeing automatically communf' cated to the tally and carbon strips. Whenthe rock shaft 50 is turned back to normal position the main feed rollerand the stops 64 are restored to normal position in the usual way andthe arm 104 and pawl 106 will be moved back to their normal positions,the pawl tooth 108 riding over the back of one of the teeth of the linespacing wheel 30 and dropping into the first notch between the teethahead or in advance of the last notch with which said pawl tooth hadoperatively engaged.

Referring now to certain features of the operation of my improvements,it will be understood that after the tally strip 88 and the carbon strip89 have been introduced into their holder and initially positionedrelatively to the short or supplementary platen section, as illustratedfor example in Fig. 4, the arm 52 may be pushed rearwardly locking themain feed roller and stops 64 in'the positions shown in Fig. 5 andautomatically line spacing the tally and carbon strips. Then a billsheet 110 may be introduced into the machine over the paper table andthe paper apron 68 and alined against the stops 64. The right-hand sideportion of the bill sheet, it is assumed, is provided with a daily totalcolumn and the bill sheet is so positioned widthwise that the righthandside portion containing the daily total column overlies the unwoundportion of the tally and carbon strips. This will be understood clearlyfrom a consideration of Fig. 3 wherein the bill sheet is represented indotted lines. From an inspection of Fig. 4 it will be seen that the billsheet 110 is entered behind the supplementary feed roller. Thesupplementary feed roller constitutes a paper controlling device soarranged that work sheets (i. e. the bill sheet and tally strip) may beintroduced at opposite sides of it and fed over the supplementary platenindependently of each other, said paper controlling device cooperatingwith only one of said work sheets, namely the tally strip.

As has been stated, the supplementary platen section is slightly less indiameter than the main platen section. This is to accommodate the carbonand tally strips, so that though they are positioned on the short platensection, yet, nevertheless, that portion of the bill sheet overlyingthem will not be forced farther away from the axis of the main platensection than is the lefthand side portion of the bill sheet which liesagainst said main platen section.

The bill sheet 110 having been properly alined, the main feed roller andthe, stops may be released and then the main platen section may be linespaced by operating the line spacing lever 39 in the usual way orturning one of the platen finger wheels (not shown) to bring said billsheet into position for receiving the first line or item of the entry tobe written. After the first line has been written by operating the usualprinting instrumentalities, causing impressions to be made on the billsheet at the under side of the platen through the usual inking ribbon(not shown), the bill sheet may be line spaced by operating the lever 39and any subsequent lines constituting the entry may be written upon it.During these line spacing movements of the bill sheet and main platensection, the supplementary platen section will remain quiescent orstationary and the right-hand side portion of the bill sheet will slideover the carbon and tally strips which will be maintained close againstthe under side of the supplementary platen section by the right-handside portion of the bill sheet, but will not be advanced or line spaced.When the items on the bill have been completed the platen will be movedendwise toward the left until the daily total column on the bill sheetis in position for receiving the imprints of the types. As the dailytotal is printed the type impressions constituting it will be madesimultaneously on the bill sheet 110 through the inking ribbon andsimultaneously on the tally strip 88 through the carbon strip 89interposed between the bill sheet and the tally strip. Thus it will beseen that all the impressions on the bill sheet are made through theinking ribbon, while the items on the tally strip are carbon copies.

The arm 52 may now be operated positioning the leading edge stops andreleasing the bill sheet just written so that it may be withdrawn fromthe machine. The operation of the hand lever 52 automatically effects aline space turning movement of the short platen section and advances orline spaces the tally and carbon strips which will be moved forward overthe right-hand side portion of the bill sheet just written. Consequentlywhen the next bill sheet is entered, alined and written upon as beforeand the daily total is printed, said daily total will be reproduced onthe tally strip a line space distance from the daily total of thepreceding bill. The operations above outlined may be repeated atpleasure.

It will be apparent that when the entries on the days bills have beencompleted their daily totals will be reproduced in condensed order onthe tally strip.

Various changes may be effected within my invention and parts of it maybe used without other parts.
